The UFC will return to the top of the combat sports conversation Sunday morning, when Alistair Overeem's heavyweight battle with Andrei Arlovski headlines the Rotterdam fight card.

But for one night, everyone was talking about boxing, after watching Canelo Alvarez's crushing KO of Amir Khan, which sparked talk of an Alvarez-Gennady Golovkin fight from everybody -- even the guy who just got beat.

"It's time that Canelo steps in the ring with Triple G," Khan said after regaining consciousness. He wasn't alone.

More from FoxSports

Here's what people were saying after the fight.

Canelo says he is willing to make GGG an offer for a fight in the fall. "I'll be happy not just to fight him, but to beat him."

Canelo says he has "no issue" fighting @GGGBoxing at a 160-pound limit. That's huge. If true, an enormous obstacle has been removed.

— Chris Mannix (@ChrisMannixYS) May 8, 2016

De La Hoya said he's clearly empowered by popularity of @Canelo in GGG talks. "I have four aces and they have a pair of twos," he says.

Congrats to @Canelo for doing what we all knew you would and KOing Khan. Was I imagining things or did you call out @GGGBoxing afterwards?

Jerry Jones was here tonight and Oscar said his stadium in Dallas is a "huge possibility" to host Canelo's next fight. #CaneloKhan

Be a middleweight, Canelo. Fight @GGGBoxing. Fight @AndyLeeBoxing at 160. If you're a 155 pounder, move down to 154 & admit you're a bit 🐓.

— Lou DiBella (@loudibella) May 8, 2016

By the way, Glenn Trowbridge, who had the fight 4-1 for Canelo at the time of the stoppage, you need to be investigated. Like, immediately.
